| Brief Introduction | | | | reduce a large number of investment costs. |
| LM-series vertical mill is one advanced mill, | | | | 2. Low Operation Cost |
| adopting top technology domesic and abroad, and | | | | ? High efficiency: roller compacted materials |
| based on many years’ mill experiences. It can | | | | directly onto the grinding disc, so power |
| crush, dry, grind, and classify the materials. | | | | consumption is low. Compared with ball mill, it |
| | | | saves energy consumption by 30% ~ 40%. |
| Working princeple | | | | ? Less wear and tear: As the roller is not in direct |
| As chart 1 shows, motor runs under the condition | | | | contact with the disc, and material of the roller |
| that speed reducer drives the Nether millstone. | | | | and liner is high quality, so life lime is long. |
| The materials fall into the center of device | | | | 3. High Drying Ability |
| through lock air feeder, and hot air comes into mill | | | | As the hot air inside contacts directly with the |
| through air inlet. Under the function of centrifugal | | | | material, drying ability is higher, and it saves |
| force, the materials move to the edge of the | | | | energy. By regulating the air temperature, it can |
| Nether millstone as it runs and rollers will grind the | | | | meet requirements with diffirent humidity. |
| materials when they come by the annular chute. | | | | 4. Simple and reliable operation |
| The grinded materials will be taken up by air | | | | ? It is equipped with automatic control systems, |
| circulation and the bigger powders will fall down | | | | so remote control makes it easy to operate. |
| for regrinding. Qualified powders will be collected | | | | ? It is equipmented with one device,which |
| by collecting device as to be final product. | | | | prevents the roller from contacting with the liner |
| Materials containing water will be dried when they | | | | directly, and avoids the destructive impact and |
| contact with the hot air. Different humidity | | | | severe vibration. |
| materials can be dried to the requirement through | | | | 5. the stability of product quality |
| adjusting the temperature of hot air. Adjusting | | | | As the material stays in the mill for a short time, |
| the separator can get the required fineness | | | | it is easy to detect and control the product |
| powders. | | | | particle size and chemical composition, to reduce |
| Main Advanced Features: | | | | duplication of milling, stable product quality. |
| 1. Low Investment Cost | | | | 6. Maintenance convenience |
| Vertical Roller Mill itself can crush, dry, grinding, | | | | By reparinging fuel tank, rotating the arm, it is |
| classifying, so the system is simple, and | | | | fast to replace the roller sleeve, and liner, and |
| occupation area is about 50% of ball mill system. | | | | reduce the downtime loss. |
| In addition, it can be installed outside, so it will | | | | 7. |
